plate constituting an attachment adapted to be secured to the end of thejournal box to receive the thrust and wear and take up undue play, asfor example between the j ournal box and a wheel hub, although theattachment is capable of employment in connection-with similararrangements or devices.

A convenient embodiment of the invention comprises a plate of thecharacter designated provided with ribs or projections adapted to haveslidable connection with complementary grooves or recesses on the ournalbox for connecting the plate to the journal box, said connectionpreferably beingof a character to retain the plate in the desiredposition in reference to the box and wheel hub,- although the inventionalso: contemplates still other means for securing the plate. againstdisplacement-or accidental removal from the box.

Fig. 3 is an elevation of the opposite side of the hub platedetached, and, Fig. 4 is afragmentary plan view of Fig. 1. Referringmore specifically to the drawings wherein like reference charactersdesignate corresponding parts in the several views, A represents ajournal box of any ordinary or preferred construction. B the wheel and Cthe journal or.axle thercfor.

The inner end or face of the journai boxis provided with a pair ofdownwardly tapermg grooves or ways D of approximately dovetail crosssection arranged near the opposite edges of the box.

i E is the hub or wear plate any suitable material for example, brass,the same being approximately U-shape, open at its bottom to accommodatethe journal C,'

and of an area and shape to constitute a broad fiat bearing for thewheel hub, it being observed that the plate is of substantially the sameheight and width as the'journal box. On that face of the plate whichadjoins the end of the box I form a pair of tapering or wedge-shapedribs F, approximately dove-tail in cross section adaptedto he sliddownwardly into binding engage ment with the complementary side walls ofthe grooves or ways D in the journal box which will ordinarily suflicein retaining the hub plate in place. To however provide the additionalsecurity of a lock for positively;

preventing accidental displacement or removal of the hub plate I providethe lower opposite ends thereof with outwardly projecting flanges G,perforated at 9, adapted to overlie the adjacent side walls of thejournal box to receive a pin or bolt G passed through said flanges andthrough the walls of the box .to removably secure these parts together.The

top of the hub plate is formed with an oil cell J opening through ductsy' to the face of the plate as shown. The wall of the cell which facesthe wheel is provided with an opening K for the introduction of anysuit-- able tool designed to remove the plate, as"

when the same becomes worn and a new one is to be substituted therefor.L is a channel across the inner edge of the plate through which oil maypass to the journal or into which oil may flow from the journal.
